Patent GB-844294-A (GB)
Title: Improvements relating to the production of granulated urea
IPC: C01C1/12
Filed: 1958-11-20
Abstract: A process for the manufacture of urea in granular form from ammonia and carbon dioxide in which the residual gas from the synthesis, containing ammonia, carbon dioxide, water and inert gases, is worked up by selective absorption of the ammonia and the ammonia and carbon dioxide are separately returned to the process, is characterised by the feature that after removal of the greater part of the ammonia, the residual ammonia remaining in the gas mixture is partly or completly washed out with aqueous sulphuric acid and is obtained as an aqueous ammonium sulphate solution, which is added to the originally produced aqueous solution of urea, after which the mixture is concentrated and granulated. Preferably the ammonia is selectively absorbed by treatment with ammonium nitrate solution; the amount of ammonia so absorbed is preferably adjusted by altering the absorption conditions in such a way that the treatment with aqueous sulphuric acid produces as much ammonium sulphate as is necessary, when mixed with the urea, to give a concentration of 3-20%.  Any excess of ammonia may then be removed by water washing.

Title: Arrangement for checking the operation of control circuit
IPC: B41J9/52
Filed: 1974-09-04
Abstract: 1480354 Electric selective signalling COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII-HONEYWELL BULL 4 Sept 1974 [5 Sept 1973] 38661/74 Heading G4H The invention relates to an arrangement for checking the operation of control circuits, which, as described, are strike amplifiers for the hammers of a belt printer. As described, the belt contains ten identical sets of 48 characters and moves past ten sets of 16 hammers, the distance between the hammers being less than the distance between the characters. Each cycle (the time separating the coincidences of two adjacent characters with the same hammer) is split into 16 subcycles (the intervals separating two successive strikes by two hammers) in each of which there are ten simultaneous concidences. Data to be printed in a store MEMLI is compared in each subcycle with the characters on the belt fed from a memory MIB, the ten results (print or not) for each subcycle being fed via a register REF to a 16 Î 10 matrix MAT addressed by the outputs of a decoder connected to a counter CSC. The contents of matrix MAT are fed to the hammer strike amplifier circuitry AMPF for printing. Each amplifier is associated with means for detecting malfunction giving rise to a desired character not being printed or being misaligned. In each subcycle in turn, the detector outputs are fed to the appropriate row of a matrix MADE also addressed by the decoder outputs. For each row, the columns containing faulty operation signals pass these on to a register REC which also receives the (row) output from CSC. Thus REC contains the row and column address of a faulty hammer circuit. The outputs to REC are also fed to an OR gate to set a flipflop ECE when a complete line has been printed. A further flip-flop MCE is set if another circuit is faulty. Matrix MADE consists of ten columns each containing 16 AND gates having commoncolumn outputs F1-F10 and inputs from the detectors and the decoder (D0-D15).
